Planet stacking with Registax.

load-01.jpg
The first step is to load in your AVI or stack of .bmp's or jpg images by clicking Select.   Here I am using an AVI of Mars.

Now choose a size of alignment box that fits around your planet.  Here I am using 128.
Make sure that the Colour box is checked under Use.  For planets I have found it best to use the Gradient and I chose to keep the top 30% (Lowest Quality 70)  You can use either Processing on Automatic or Manual.  Here I have chosen to use Manual.   Then click Align.

After the initial alignment click the Optimize Tab along the top.  For this Demo I left most of this untouched.  Search area 2 and Optimize until 1.  Next I set the Create to around 50 and hit Create.  What this does is create a reference frame that the program will use to optimize and stack the other frames too.

Here you are on the Wavelet Tab for the first time.  You can make alteration here to your image so that it looks good.  When you have finished here click the Continue button.

Most of my planetary images have the red and blue chanels out of alignment.  Here click the RGB shift tab running down the right hand side and when the RGB shift box opens click Estimate.  Sometimes the program gets it wrong so you have to click Estimage a second time.  When finished close the RGB box and now move the Wavelet sliders to enhance the images details.  Be careful not to introduce false artifacts here.  Remember to click the Continue button at the top.

This next screen tells you to continue to process the rest of the frames with either Optimize or Optimize and Stack.  Now you can Resample or Drizzle the resultant image from X1 to X4 in .1 steps.  Now press Optimize.

Here the program is sorting through the rest of the frames in the AVI to find the best frames for stacking.  Wait till the program has finished and click the Stack Tab at the top.

There are a number of setting on this tab but I mainly leave them alone as I have not found them to be helpful as yet so I just click Stack.  When done click the Wavelet tab at the top to move onto the next step.

Now I am back at the Wavelets again.  Again I hit the RGBshift tab along the right hand side because now that I have more frames stacked it shows more of the red and blue that has been shifted.

Next step is to sort out the Histogram.  Sometimes the camera can get the colours very strong so I tweak the Histogram to try and make the image look more natural.

In this image you can see that the Wavelet sliders have been moved a greater amount to the right.  This is because I have changed from Default to Gaussian filter.  This allows more control over the  Wavelets.  If you are happy with your image you can now save your image to harddrive by clicking the blue Save Image button at top right.
final-12.jpg
Click the Final tab along the top of the program.  On this page you can rotate the image to correct for telescope positioning as you can see here I rotated Mars.  After any of the adjustments from here on you can save your image to harddrive by clicking the blue Save Image button at the bottom left.
final-HSL-13.jpg
Click the Advanced HSL (Hue, Saturation and Lightness)   I fount that I had to put the mouse pointer in the white area and press the left mouse button and while holding down the button move the mouse to get the lines to appear.  To move the lines just click on and hold one of the red circles.  Adjust to taste.

Should you wish to you can now save your image by clicking the blue Save Image button.
final-resize-15.jpg
This last image shows that you can now resize your image by clicking Resize.  You can resize from 25% up to 200% using one of the 4 filters.  Again  clicking the blue Save Image button allows you to save your image.
